Kell Brook is furious with the recent news that his career rival, Amir Khan, failed a drug test in connection with their high-profile showdown from February 2022.

On Tuesday, the 36-year-old Khan was hit with a two-year ban, from drug testing agency UKAD, as a result of testing positive for the banned substance ostarine.

UKAD ruled out ‘deliberate or reckless conduct’ and concluding the substance in his system was too low to have enhanced his performance.

Khan has no idea how the substance entered his body and openly denied that he knowingly took the banned substance.

The actual bout was a one-sided affair, with Brook stopping Khan in the sixth round.

Khan would later announce his retirement from the sport.

Brook was unaware that Khan had failed a drug test until UKAD's resolution was revealed on social media on Tuesday.

"It makes me feel sick," Brook told IFL TV. ‘I have got three beautiful kids, he’s gone in there to try and hurt me on some sort of drug he’s been on. It is a f------- joke.

"I just think his back is against the wall. It is the same for everyone who has been caught out, “I didn’t know, it was this or that.” At the end of the day it was in you and you were going to fight and hurt me in a sport where you can legally get killed. It is in your system. You’ve gone in there with bad intentions to win the fight at all costs which has come back to bite him.

"It could have been a completely different story, I could be in a wheelchair now, him seriously destroying my life or killed me or crippled me forever. He came into that ring cheating, trying to boost himself up or whatever he’s done trying to get the advantage, not doing it in a 12 week camp. He needs to pay bad.

"He is going to have to live with that. People will think how long has he been on these drugs, it is going to tarnish his career terribly. He got an absolute pasting. Imagine if he weren’t on these drugs, he probably would have gone out in the third round. He still took a massive hiding. He’s got to live with that beating for the rest of his life and everyone looking down with shame on him."
